Incerc sa fac un form,3 campuri de tip text si unul file.Il fac cu
$this->load->library('validation');
Merge pana la partea de upload.Din ce vad nu imi trimite deloc campul file.Si nici nu vad cum as putea valida campul file.Am pus o functie cu callback dar nici asa nu merge.Ideea e cum as putea face pentru campul file sa verifice ce extensii sa lase sa se uploadeze.
Daca de exemplu fac o functie pentru upload,si afisez in ea erorile,si o pun la callback,tot nu merge.Exista alta cale de a valida un type file decat cu callback?

Foloseste libraria upload.

Ai acolo:
Cod:
$config['upload_path'] = './uploads/';
$con fig['allowed_types'] = 'gif|jpg|png';
$config['max_size']   = '100';
$config['max_width']  = '1024';
$config['max_height']  = '768';

Stiu.aia am folosit.Dar nu merge.Cred ca nu am inteles eu bine modul de functionare a librariei validator.
Daca are cineva chef sa se uite peste cod,e mai jos:

Cod:
<?php
//upload photos
function upload_photos()
{
            
$view_data["action"] = "add_sponsors";
$this->load->helper(array('form', 'url'));      

$config['upload_path'] = "./upload/";
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size']   = '100';
$config['max_width']  = '1024';
$config['max_height']  = '768';
      
$this->load->library('upload', $config);

if ( ! $this->upload->do_upload("userfile"))
{
$error = $this->upload->display_errors();
 $this->validation->set_message('upload_photos', $error);
return false;
}
else
{           
          
$image_lib_config['image_library'] = 'gd2';
$image_lib_config['maintain_ratio'] = TRUE;
$image_lib_config['quality'] = '70';
      
$upload_file = $this->upload->data();
$file_name = $upload_file["file_name"];
$image_width = $upload_file['image_width'];      
$image_height = $upload_file['image_height'];
      
      
$image_lib_config['master_dim'] = 'auto';
$image_lib_config['width'] = '300';
$image_lib_config['height'] = '200';
$image_lib_config['source_image'] = './upload/'.$file_name;
$image_lib_config['create_thumb'] = FALSE;
            
$this->image_lib->initialize($image_lib_config);
        
if(!$this->image_lib->resize())
 {
$error = $this->image_lib->display_errors();
$this->validation->set_message('upload_photos',$error);
return false;
}
else
{
return   $post_image = $file_name;

Pana la urma am renuntat la validarea campului photo pentru ca nu am reusit.In schimb nu merge nici upload-ul.Daca folosesc functia separat(fac un controller,doar pentru functia asta),merge,cand o apelez din alta functie nu mai merge.Imi da eroarea:
An Error Was Encountered
Error Number: 1048

Column 'path' cannot be null

INSERT INTO gl_sponsors (id, name, description, website, path) VALUES ('', 'dfgdfhbdfhbfd', 'ghdfhgdsfhb', '', NULL)

[mihaitha]

Cum o apelezi de iti da eroarea asta?

Apropo, sper ca nu te injur, dar stii ca daca vrei sa faci un upload form-ul trebuie declarat cu enctype='multipart/form-data' , nu?
// LE: disregard that, acum am vazut ca declari formul cu form_open_multipart(). Sorry.

Eroarea asta e clar de unde vine: campul path din tabela gl_sponsors e declarat ca 'not null', iar tu cand apelezi
Cod:
$this->db->insert('gl_sponsors', $data);

sau ceva de genu asta, $data['path'] e declarat undeva explicit ca = null. Da codul metodei unde apelezi asta din controller sau din model.

Am rezolvat pana la urma,incarcasem de 2 ori libraria upload.A mai ramas faza ca nu imi merge sa folosesc callback pentru validare la camp de tip file.Aia chiar nu stiu de ce.Sau de exemplu pentru codul de mai sus de la functia add sponsors,daca la functia upload_photos fac:

if ( ! $this->upload->do_upload())
{
$view_data["action"] = "add_sponsors";
$view_data["error"] = $this->upload->display_errors();
$this->load->view('admin/front/admin_front_view', $view_data);
$this->validation->set_message('upload_photos',"%s trebuie sa fie jpg,gif sau png");
}

Nu ar trebui sa mearga?La mine nu merge.

Nu asta ma intereseaza.Asta stiu si eu.Ma intereseaza cum se face in codeigniter.
